Here, applying the combination of scanning probe microscopy/spectroscopy and the density functional theory calculations, we gain a profound insight into the electronic and topographic contributions to the imaging contrast of the epitaxial graphene/Ir(111) system. We show directly that in STM imaging the electronic contribution is prevailing compared to the topographic one. In the force microscopy and spectroscopy experiments we observe a variation of the interaction strength between the tip and high-symmetry places within the graphene moiré supercell, which determine the adsorption sites for molecules or metal clusters on graphene/Ir(111).</dcterms:abstract> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-03-13T08:57:27Z</dcterms:available> <dc:creator>Thissen, Andreas</dc:creator> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-03-13T08:57:27Z</dc:date> <dc:contributor>Voloshina, Elena N.</dc:contributor> <dc:creator>Garhofer, Andreas</dc:creator> <dcterms:title>Electronic structure and imaging contrast of graphene moiré on metals</dcterms:title> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
